To all whom it may concern:

Be it known that I, Greene KIRKEGAARD, a citizen of the United States, resi g at, the city'of New York, in tlie' boroug of Brooklyn and State of New York, have invented certain new and useful Improvements in Gapping-Machine Heads, of which scri tion 1s invention relates to bottle capping machines which are used to apply to bottles stoppers consisting of metallic caps containmg a (packing disk-and having a flange to. be forced into locking engageneck of the bottle;

I The cap which the lea hollow cylindrica cap upon the bottle.

which the cap is to be intended to be applied by U. S; Patent No. 873,245, dated-Decombat-10, 1907, and issued to me, there is methree sectorsfoi'mlng a die adapted'to press the The sectors are held together in cylindrical form by springs embracing them, which permit the sectors to open or separatewhexiever the bottle upon placed is abnormally in ellect, an expanding breakage of the bottle. patented die or head is intended to apply is provided with three depending ears wii'ch "are to be forced into engagement with the bottle an'd the sectors chines, comprisin large the die being die, which prevents of; the die are rovided with grooves corresponding to t ese cars, the formation be in); such that the flanges of the cap between the adjacent cars is not required to be acted,

upon by the die.

In the present'invention the'type of cap chine has a continuous depending tnge, instead of thethree ears above referred to, and the sectors of the die or head must act upon the entire circumference oithe flange. In PP v die of t e kind described, in those instances where the die mustexpand to apply the cap to an extra-large bottle,'there are three places around the ed c of the applied cap which are not touche by the'sectors, these pla es being opposite the openings between 'the adjacent'cnds oi the sectors caused by the expansion of the die.

A bottle with it applied in thn 'way will sometimes on account of three protuberances which H Specification of Letters Patent. Application filed Kay 6, 1908. Serial No. 431,160.

prove the die or head described in the above is the object of this invention toim mentioned patent in such a manner a's to avoid this objection, and the invention consists in combining with a die or head of the character described a second set of sectors which are s'eeted in an internal groove in the main sectors, located immediately above the mouth of the die, the members of this additional set of sectors In this Way, those portions of a cap which may not be acted upon by the main sectors Will be acted upon by the additional secto1' s,.and the entire flange of .the cap will, therefore, be

uniformly driven into'locking engagement the bottle.

' My present invention also includes an improvement in the term of the springs which are used to hold the sectors together, all as will be fully described and pointed out in the claims. v

In the accompanying-drawing, Figure 1 is a vertical central sectiontof my improved head for capping machines Fig. 2 is a section on line of Fig. 1. Fi 3 is a section on line-y-y of Fig. 1, an Fig. 4 is a side elevation of one form of cap which my improved head is intended to apply, to a bottle I The capping head comprises a casing 1 cylindrical in form and having its lower side open, but provided with an annular lip 2 to hold the (li v therein. This casing is carried Within the casing are placed three sectors 4,4, 4 of a cylinder, Each of these sectors is provided with ono'or more fiat springs 5 which are applied horizontally and tangentially to the outslde of the sector, being lwldin place by a pin (5, audits extremities hearing, under strain, againstthe inner wall of the casing. Thus'thcse springs tend to force all of the sectors 4- toward aconnnon center, and, in fact, do hold, the sectors with their extrcmities in contact with each other along radial planes 120 apart. The lower ends oi. the sectors are provided with lateral flanges 7 which rcstupon the lip 2 of the casing, furnishing a means for freely su' porting the sectors within the casin -T c three sectors together form a cylin'rical die havbeing placed so as to break joints with the first set.

' ing a smooth bore which terminates at the lower end in a flaring mouth or annular-surface 8. Immediately abo e this flaring mouth, the die is provided with an internal annular groove 9 rectangular in cross section and in wh ch 18 placed three sectors 10, 10, 10 of a ring. These sectors, which may i be regarded as supplemental to the main sectors 4, are placed in the groove sov as to bridge the respective joints betweenthe main sectors 4. These smaller sectors, when. thus inserted in the larger ones, are "flush with or unsightly portions upon the cap, and, in

this respect, the die will act very much in the same way as the patented die referred to. Then a bottle having an abnormally present "spaces between their wide mouth is encountered, which often occurs by reason otthe crudity with which these bottles are manufactured, the main sectors itopen outward or expand, the springs 5 flexin' .sufiiciently to permit this movement, w ile. furnishing sufficient resistance to properly act upon the flange of the cap. In thus opening or separating, the sectors at which do not touch the" flange ot' the cap. The head, nevertheless, travels downward suliiciently to bringthe second set of sectors 10 intoenga-geinent with the cap flange,'and, since they are arranged across the spaces between the sectors 4, they will act upon those parts of the flange of the cap which escape the action of the main sectors 4:, the result being that the entire cap will be acted upon by the die, and, notwithstanding the differ ent size of bottle, the cap will come out of the machine presenting as good an appearance and being as tightly sealed as if the bottle were of ordinary size. p

I have found that individual springs for each of the sectors 4-, such as described, act better than springs which surround the enadjacent ends,

tire cue and are common toall the sectors. The open-rin g form of springs shown in the patent referred to, spread more at one part of the circumference than at another, and

tend to throw the sectors out proper rela tive position. The individual springs 'provided by the present invention overcome this and supply a uniform pressure upon each sector, toward the ccmm on center or axis of the die.

Vila-t I claim is:

1. A head for bottle capping machines, comprisingacy-lindrical expanding die com- ;posed of two setsof concentrically arranged sectors in concentric annular zones one with in the other, the members of each set symmetrically. breaking joints with those'of the other, and adapted to act in succession upon the cap in applying'the same to the Bottle.

2. A head for bottle capping machines,

comprising a plurality ot=sectors forming together a hollow cylindrical .die, said die having an internal concentric groove in its wall,

and a plurality of supplemental sectors located in said groove and breaking joints with the first-mentioned sectors, substantially as described.

3. A head for bottle capping machines, comprising a pluralit of sectors together forming a hollow cylindrical die having-a flaring mouth and an internal concentric- .groove arnn'ged at right-angles to theaxis of the die and immediately above its mouth, and "a plurality of supplemental sectors lo cated in said groove, breaking joints with the first-mentioned sectors, and being flush with the internal surface of the die, substantially" as described.

4c. Ahead for bottle capping machines,

comprising a casing, a plurality of sectors to- Y gether forming a hollow cylindrical die 16- catcd within the casing, and a fiat spring for each sector attahed at its middle to the sector, arranged in a tangential position thereon and bearing under compression at its extremities against the inner wall of the casing.

In witness whereof, subscribe my signature, in the presence of two witnesses.
